物理量及物理方程的时间反演变换

Time Inversion of Physical Quantity and Physical Equation

摘要: 通过对当前普遍采用的物理量的时间反演变换定义的详细分析，发现了物理量的时间反演变换导致其反演量的变化过程逆转的前提条件：在时间保持正向流逝的条件下时间反演变换将改变物理过程的方向。并以新的时间反演变换的定义内容为基础，对物理量的微分、导数及常用算符等的时间反演变换进行了详细分析并获得了重要结论。在此基础上对几个重要物理方程的时间反演变换进行了讨论，描述最基本物理过程的方程具有时间反演变换不变性以及热力学过程的单向性与时间箭头无关等就是讨论中获得的重要结论。

Abstract: Based on the detailed analysis of the definition of the time inversion transformation of physical quantity, the precondition that the time inversion transformation of physical quantity leads to the reversal of the change process of its inversion quantity is found: the time inversion transformation will change the direction of the physical process under the condition that the time keeps the positive passage. Based on the definition of the new time inversion transformation, the time inversion transformation of the differential and derivative of physical quantities and the commonly used operators are analyzed in detail and important conclusions are obtained. On this basis, the time inversion transformation of several important physical equations is discussed, the time inversion transformation invariance of the equation describing the most basic physical process and the unidirectionality of the thermodynamic process independent of the time arrow are important conclusions obtained in the discussion.
